BALL.

SPEGIFICATION forming part of Letters Patent No. 700,660, dated May 20, 1902.

Application filed April 11, 1902. Serial No. 102,434. (No model.)

To all whmn it may concern:

Be it known that I, ELEAZER KEMPSHALL, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Golf-Balls, of which the following is a specification.

This invention relates to playing-balls for golf and similar games, and especially to balls made according to Letters Patent No. 695,866,

, dated March 18, 1902, which balls consist of a resilient shell having a core of an elastic substance held under compression.

The main'object of the present invention is to provide efficient interlocking means for the joints; and its peculiar nature consists in the employment of an interlocking ring having inwardly-turned edges into which portions of the edges of the shell are forced when the ball is completed.

In the drawings accompanying the present application and formingapart thereof, Figure 1 illustrates a complete ball, partially broken away in order to expose the interlocking device. Fig. 2 illustrates the final step in manufacturing the ball. Fig. 3 is aview of a core formed with a groove to receive the interlocking device, and Fig. 4 is a perspective View of the said device. I

In manufacturing a golf-hall according to the present invention a core 1 is provided,preferably at its largest diameter, with an annular groove 5. The material of the core is preferably gutta-percha; but other suitable material may be used, according to different requirements. A shell 2, made of celluloid or its substitutes, is compressed over the core, which preferably is made oversize, a ring 6 for interlocking the joint is placed in the annular groove 5, and the hemispherical shellsegments are preferably so arranged that their edges are contiguous to the center line of the annular groove 5. The interlocking ring may be made of metal or any other relatively rigid material, and consists, preferably, of a continuous ring without seam, having flanges or turned-in edges 7, as illustrated in Fig. 4. The assembled shell, ring,and core are now placed in forming-dies 8 and submitted to heat and compression.

The ring 6 in itsannular groove 5 not only prevents the squeezing out of the material of the core 1 between the edges of the shell 2, but reverses theeffect-z'. e., the compression applied to theassembled ball within the dies will force the softened material of the edges of the shell into the annular groove of ring 6. Part of the material of the edges will enter the spaces behind the turned-in edges 7 of ring 6, and thereby form a most efficient interlocking means between shell and ring. An additional advantage'd'ue to the employment of ring 6 is the size of the abutting faces of the joints, which faces are considerably wider than in ordinary joints, thereby producing a weld of great strength. It will be noticed, therefore, that the present improvement results in a ball having great resistance in the region of the joints of its shell.

It will be observed that'my improved ball comprises a shell which consists of segments which are both weldedand locked together,

the locking-ring being interlocked (preferably hook-fashion) with both segments at or near the weld between the segments. Thus the shellis well-clenched upon'the core and rupture of the weld is practically impossible. Thesegments may be otherwise caught together within the scope of my present improvements.

Having described my invention, I claim- 1." A playing-ball comprising a shell, a core having an annular groove,- and a ring within the grooveand along the joints of the shell and adapted tointerlock the joint.

2. A playing-ball comprising a core having an annular groove, a pluralityof shell-segments surrounding the core,and a ring located within the groove and interlocking the joints of the shell-segments.

3. In a'playing-ball, interlocking means for the shell-segments comprising a continuous ring having flanges forming an annular groove and adapted to'receive portions of the shell material of abutting edges of the shell.

4. A playing-ball comprising a spherical core, an annular groove insaid core,.a continuous ring in said groove,"said*ririg having flanges and shell-segments inclosing the core and having their joints located between said flanges.

5. A playing-hall comprising a plurality of 8. In a playing-ball, the combination of a filling, a shell thereon formed of plastic material, said segments being welded together, and a device applied tosaid segments within said shell and clenching them together.

9. A playing-ball comprising a core and a shell thereon formed of segments of plastic material, said segments being Welded together, and a device connecting said segments and interlocked witheach thereof.

10. In a playing-ball, the combination with a springy core of a shell thereon formed of segments of plastic material, said segments being both Welded and mechanically locked together.

11. In a playing-ball, the combination with a springy core of a celluloid shell thereon, said shell consisting of segments which are both welded and mechanically locked together.

12. In a playing-ball, the combination with a core of a shell thereon formed of segments of plastic material, said segments being Welded together, and a device connecting said segments and hooking into each thereof.
